* src/xterm.c (xi_compute_root_window_offset_enter): New
function.
(handle_one_xevent): Apply root window crossing optimizations to
XI_Enter and XI_Leave events too. Not strictly necessary but
since we apply them to motion events it would be consistent to
apply them to crossing events as well as recommended by the
ICCCM.
C23 is adding the C++ keywords bool, true, and false;
prefer them to <stdbool.h> if they are available.
* admin/merge-gnulib (GNULIB_MODULES):
Add stdbool, which emulates C23 on pre-C23 platforms.
(AVOIDED_MODULES): Remove stdbool; Gnulib has renamed
this module to stdbool-c99 and nobody uses it so it does
not need to be avoided.
* m4/c-bool.m4: New file, from Gnulib stdbool module.
* lib-src/seccomp-filter.c, src/conf_post.h, src/dynlib.h:
* src/emacs-module.c, src/nsterm.m, src/systhread.h:
* test/src/emacs-module-resources/mod-test.c:
Use the C23 style and use bool without including <stdbool.h>.
The Gnulib stdbool module causes config.h to include stdbool.h
on pre-C23 platforms.
* src/emacs-module.h.in:
Don’t include <stdbool.h> if C23 or later, or if
it has already been included.
These changes noticeably improve turning the mouse wheel on top of
scroll bars etc over slow network connections.
* src/xterm.c (x_dnd_note_self_position, x_dnd_note_self_wheel)
(x_dnd_note_self_drop): Use x_translate_coordinates.
(x_compute_root_window_offset): New function for calculating and
caching root window offsets of edit window.
(x_translate_coordinates): New function. Use cached values
whenever possible.
(xi_compute_root_window_offset)
(xi_compute_root_window_offset_pinch): New wrappers for XI2
events.
(x_construct_mouse_click, handle_one_xevent): Use
x_translate_coordinates wherever appropriate.
* src/xterm.h (struct x_output): New fields for keeping track of
the root window offset of the edit window.
* src/composite.c (composition_gstring_adjust_zero_width): New function.
* src/composite.h: Declare it.
* src/font.c (Ffont_shape_gstring): Use it before putting gstring to cache.
* src/font.c (check_gstring, check_otf_features, otf_tag_symbol)
(otf_open, font_otf_capability, generate_otf_features)
(font_otf_DeviceTable, font_otf_ValueRecord, font_otf_Anchor):
Move closer to the primitives that use them. Add commentary for
the purpose of this code.
* doc/emacs/frames.texi (Fonts): Update documentation to say
what font-use-system-font really does and where it can be used.
* src/haiku_font_support.cc (language_code_points): Fix coding
style.
(font_style_to_flags, be_font_style_to_flags): Accept const char
*.
(be_send_font_settings, be_listen_font_settings)
(be_lock_font_defaults, be_unlock_font_defaults)
(be_get_font_default, be_get_font_size): New functions used to
retrieve default font data.
* src/haiku_io.c (haiku_len): Handle FONT_CHANGE_EVENT.
* src/haiku_support.h (enum haiku_event_type): New event type
FONT_CHANGE_EVENT.
(enum haiku_what_font): New enum.
(struct haiku_font_change_event): New struct.
* src/haikufont.c (Ffont_get_system_normal_font)
(Ffont_get_system_font, haiku_handle_font_change_event): New
functions.
(syms_of_haikufont): Provide `dynamic-setting' and define new
variables and subrs.
* src/haikuterm.c (haiku_default_font_parameter): Use system font.
(haiku_read_socket): Handle FONT_CHANGE_EVENTS.
(haiku_term_init): Start listening for font configuration changes.
* src/haikuterm.h: Update prototypes.
* src/xsettings.c (Ffont_get_system_normal_font)
(Ffont_get_system_font): Update doc string.
(syms_of_xsettings): Replace calls to intern with a static
string.
It turns out my previous theories of why ClientMessages were
generated were wrong, and they are just generated so we can set
finish to X_EVENT_GOTO_OUT to have them delivered immediately.
This allows for the code to be simplified greatly, by not
unpacking pointers to the raw window into the client messages.
* src/xterm.c (x_unprotect_window_for_callback): Return the
window removed from the queue, or nil if none.
(x_scroll_bar_to_input_event)
(x_horizontal_scroll_bar_to_input_event): Use window provided by
x_unprotect_window_for_callback.
(handle_one_xevent): Pass dpyinfo to functions that need it.
(x_free_frame_resources): Remove "first scroll bar request"
code.
* src/xterm.h (struct x_display_info): Likewise.
* src/xterm.c (handle_one_xevent): Ignore outdated scroll bar
events.
(x_free_frame_resources): Clear protected windows and invalidate
previous scroll bar events.
* src/xterm.h (struct x_display_info): New field
`first_valid_scroll_bar_req'.
* src/xterm.c (x_atom_refs): Add _EMACS prefix to
vendor-specific scroll-bar atoms.
(handle_one_xevent): Unprotect windows immediately upon
receiving an _EMACS_SCROLLBAR event, instead of waiting for the
event to be put on the keyboard buffer. Reported by martin
rudalics <rudalics@gmx.at>.
* src/dispnew.c (update_frame_1): Don'f flush if tty's
output_buffer_size is non-zero.
* src/sysdep.c (init_sys_modes): Setvbuf depending on the tty's
output_buffer_size.
* src/term.c (Ftty__set_output_buffer_size, Ftty__output_buffer_size):
Low-level interface for setting and retrieving a tty's output buffer
size.
(syms_of_term): Defsubr the new functions.
* src/termchar.h (struct tty_display_info): New member
output_buffer_size.
* stc/NEWS: Describe the change.
* src/xterm.c (x_dnd_update_state, handle_one_xevent): Let
x_dnd_last_seen_toplevel remain at its old value until any
XdndLeave event was definitely sent.
